Pretreatment process and main uses of horticultural product samples

The process of sample collection, sample cleaning, sample shearing, sample drying and sample shearing is mainly to remove impurities, pollutants and other factors that affect the analysis results and ensure the representativeness and accuracy of the analysis samples.

1. sample collection: when collecting samples of horticultural products, attention should be paid to the selected parts, the number and time of collection to ensure the representativeness of the samples.

2. Sample cleaning: clean the sample to remove surface dirt, residual pesticide chemicals and other substances, so as to avoid interfering with subsequent analysis.

3. Sample shearing: shearing and grinding the sample to improve the leaching rate and analysis accuracy.

4. Sample drying: dry the sample to remove water and avoid its influence in the analysis process.

5. Sample preservation: put the processed sample in a dry, closed and low-temperature environment to ensure the quality and stability of the sample.
